Light Green Interference Bandpass

The Midwest Optical Bi520 Green Interference Bandpass filters typically are used in applications employing 520nm green laser diodes or green 520nm/525nm LED light sources. The latter typically find use in machine vision inspection while the former are commonly used in bioanalytical applications. Various popularly used fluorophores (e.g., GFP, GelStar, SYBER Green, etc.) have emission maximas at or very near 520nm, and Bi520 filters can be used to effectively block excitation sources and interfering longer and shorter wavelength light while letting this light pass through to the camera’s sensor.

Useful Range : 515-525nm

FWHM : 20nm

Tolerance : +/- 5nm
